Motor Control Design for Position Measurement and Speed Control

Abstract

This paper delineates various Simulink based control model constructions of (BrushLess Direct Current) BLDC motors using microcontrollers. The constructed control models particularize the PWM phase computation, 3-phase bridge signal generation for sensor-less BLDC motors and BLDC motors with hall sensors, hall sensor based position measurement, speed control and monitoring the number of rotations of BLDC motor using digital sequential blocks. In order to assess the control model constructions, various scrutiny carried out to make sure the exactness of the models. Since the controller driver is one of the important components to control the BLDC motor effectively, the implementation of controller driver system is fundamental step in the development of actuators. Here, in this paper we are using Simulink to build the controller driver system for position and speed of BLDC motor with the help of semiconductor switching devices and digital sequential blocks.
